Ann Arbor – Michigan running back Drake Johnson’s football career has ended.

Johnson, who grew up in Ann Arbor and attended Pioneer, endured two torn anterior cruciate knee ligament tears during his career and was involved last spring in a freak incident at the track building when he was stretching and was run over by a fork lift.

“He’s not going to continue in football,” Michigan coach Jim Harbaugh said Monday after the press conference announcing hockey coach Red Berenson’s retirement. “Doesn’t think he’s able to, just medically, emotionally. Just hasn’t been able to do it at the level it needs to be done, in his opinion. He’s not going to participate in football going forward.”

The popular and engaging Johnson, who also has run track at Michigan, ran for 641 yards and eight touchdowns during his career.

Offensive tackle Grant Newsome, who suffered a gruesome knee injury last season in the Wisconsin game and spent 38 days in the hospital, is probably a year away from returning to football.

“We know it will be a process,” Harbaugh said. “Don’t think it will be this year. We’re right now hoping for next year.”

Newsome has more recently dealt with an issue on his foot caused, Harbaugh said, by being in bed as long as he was. It had not been healing but is now “much better,” Harbaugh said.

“That’s down to about where he can start running again,” Harbaugh said, who credited Newsome, and the Michigan physicians and medical trainers, for his progress since the injury. “We’re thankful for where Grant is right now but we’re not satisfied. We know he’s not. Keep plugging away.”
